Definitions

  • Patent FR-A-2 678 897 describes a device for bagging breads which comprises, in addition to a mechanism for the unwinding of a continuous sheath and the vertical guidance of the open end thereof, a fixed collar crossed by said end and a removable chute introduced into the sheath and intended to receive a bagging bread, the manual elevation of the chute and the bread which rests on the closed end of the latter allowing a welding mechanism closing the section of the sheath and cutting it.
  • the present invention aims to allow the realization of a bagging installation with automatic operation which, while taking advantage of the concept of the above-mentioned prior device, is adapted to industrial rates by minimizing, if not even eliminating, manual interventions.
  • Document FR-A-2 151 724 (PROGES) describes a machine for the formation of sachets from a sheath of heat-sealable material and for the introduction of objects into said sachets.
  • This machine comprises a drum from which the sheath takes place, an opening member fixedly disposed in said sheath applied against said member by external means, members for gripping the free end of the sheath, these members being moved for stretching a portion of the sheath, and a welding device for closing it below and above the object which has been introduced into the aforementioned portion, the lower member of this device being arranged to cut the sheath and thus release the bagged object.
  • Such a machine with vertical operation does not respond to the problem posed, namely ensuring the automatic packaging of breads, since the introduction of each loaf into the sheath portion still constitutes a manual operation.
  • the document EP-A-23 831 (KUREHA KAGAKU) relates to a method and a vacuum packaging machine comprising a device for automatic bagging of products.
  • a continuous sheath is unwound and moved axially before being opened to allow the introduction of an object to be bagged, which sheath is then sectioned to allow the evacuation of said object wrapped in its sheath portion.
  • the sheath portion is evacuated in the open state, the closure occurring after passage through a vacuum device. Furthermore, the system for introducing objects into the open end of the sheath uses reciprocating mechanisms which are relatively complicated and delicate while significantly slowing the rate of operation of the assembly.
  • the invention consists essentially in imparting to each loaf a launching movement at high speed so that said loaf penetrates in the manner of a projectile inside the end of the sheath suitably kept open.
  • the installation shown in fig. 1 firstly comprises a feed device incorporating a support, shown diagrammatically in 1, for a roller 2 ′ of a bagging sheath 2 capable of being wound up in a flattened form and of being opened by spacing the walls.
  • the free end of this sheath 2 is returned to the horizontal by a guide 3 to extend to a feed mechanism 4 which has been detailed in FIG. 2 and 3.
  • This mechanism comprises a lower roller 5 driven by the motor referenced 6 in FIG. 1, and an upper roller 7 associated with elastic means 8 which tend to press it downwards.
  • These opposite rollers 5 and 7 are associated with four smaller diameter counter rollers, arranged in pairs and carried by a die 9 inserted inside the sheath 2, which die is retained by the cooperation of the rollers and counter rollers. cited above.
  • the vertical face of the die 9 which faces upstream is provided with a wedge-shaped spacer member 10, while the opposite face carries an opener 11 with a C-shaped lateral profile, capable of being crushed to allow the welding of the sheath 2, as will be better understood below.
  • the supply device further comprises a blower 12 (fig. 1) which is oriented so that the air flow is directed towards the end of the sheath 2 which is thus kept open, in combination with the opener deformable 11 mentioned above.
  • the installation includes an introduction station which includes two endless belts 13 and 14 arranged in horizontal alignment along the axis of the assembly, that is to say in the axis of the advance mechanism 4.
  • the conveyor 13 is equipped with an upstream support 15 with a V-shaped profile which is intended to support the rear part of a loaf P temporarily stored on said conveyor 13 assumed to be stopped.
  • the belt 13 is put into operation and transmits the bread P to the belt 14, which moves continuously.
  • the mat 14 has a rough surface and moves at very high speed, in order to project the bread P towards the open end of the sheath 2 inside which it penetrates like a projectile.
  • a pad 17 (fig. 2 and 3) intended to move vertically to immobilize the bread P launched at inside the sheath 2.
  • this buffer 17 is carried by a horizontal arm 18 secured to one of the two movable jaws 19 and 20 of a welding device of conventional type.
  • Each jaw 19 and 20 is equipped with a shaping pad 21 and a welding jaw 22, the jaw 19 being furthermore provided with a vertical cutting blade 23.
  • a discharge device which comprises two parallel chains 24 driven by successive jerks by a single motor 25.
  • Each chain 24 supports three stops 26 which, suitably positioned on said chains, protrude above the table 16.
  • the advance mechanism 4 is energized so that the sheath 2 extends above the table 16 and protrudes in front thereof, the movement being stopped by detection by means of a photoelectric cell shown diagrammatically in 27 in FIG. 1.
  • the input belt 13 comes into action to transfer the bread P to the belt 14 which thus projects this bread into the end of the sheath 2 kept open by the air stream coming from of the blower 12.
  • the welding device is actuated and the descent of the upper jaw 19 causes the lowering of the pad 17, which immobilizes the bread P in the sheath 2.
  • the opener 11 resumes its normal profile elastically and ensures the opening of the end of the sheath 2. The installation is thus ready for a new operating cycle.
  • introduction station 13-14-15, the blower 12 and the detection cell 27 are advantageously mounted on a movable frame 31 capable of being adjusted in a horizontal position.
  • the installation is thus capable of being easily adapted to the bagging of breads P of different lengths.
